EHM-6618Atmospheric monitoring

Product introduction£º

Atmospheric heavy metal on-line analyzer is a dual function fully automatic on-line analysis instrument, which combines X-ray fluorescence (XRF) non-destructive testing technology, beta ray absorption testing technology and air particulate matter automatic enrichment technology, and conforms to the American EPA io-3.3 standard method. It can not only monitor the mass concentration of air particles, but also quantitatively analyze the elements in the particles.

The instrument has a detection limit of 10pg / m3, which can be widely used in air quality monitoring, pollution tracing and source analysis, environmental assessment and other fields.

Product features

  • Strong technology

    The integrated collaborative measurement of mass concentration and heavy metal concentration of airborne particulate matter can analyze the distribution of components in airborne particulate matter

  • Excellent technology

    Equipped with a variety of particle cutters for users to choose, the distribution of heavy metal particles in different dynamic diameters can be measured

  • Efficient

    The detection sensitivity of 30 heavy metals such as Pb, CD, Cr and as is pg / m3, and the element types can be expanded

  • Good service

    The main machine adopts standard 19 "chassis, which can be installed on both mobile monitoring vehicle and standard cabinet of automatic air station

  • Strong design

    20 years of XRF technology accumulation, lightning protection industrial grade electronic and electrical design, the instrument has high operation reliability and stability, 24 hours / 365 days trouble free operation, but also has intelligent fault diagnosis and self troubleshooting function

  • Excellent operation

    No stray peak optical path design, built-in multi band filter, automatic switching to achieve low background measurement

  • Strong technology

    Built in calibration module, XRF spectrum abscissa and ordinate can be automatically calibrated at the same time, the calibration frequency can be set arbitrarily, and a specific metal internal standard source is built in, which can realize automatic quality control and alarm

  • Fast

    Through the mass flow controller and temperature and pressure sensors, the sampling flow can be stably controlled, and the automatic flow calibration can be realized

  • Efficient

    With RS232 / 485, USB, GPRS, ADSL, Ethernet and other data transmission modes, it can realize the remote transmission, monitoring and inspection of operation parameters, status and data

  • Efficient

    The system software adopts advanced hierarchical modular design, with powerful and flexible data setting, calibration, saving, display, query, analysis, transmission and other functions. The data conforms to the data transmission standard of online automatic monitoring (monitoring) system for pollution sources (HJ / T 212-2005). At the same time, users can quickly and easily customize and expand any other custom functions

  • Efficient

    Professional multiple processing, no radiation leakage of the instrument
